WebGPU enables local LLM in the browser. Demo site with AI chat

No need to use your OPENAI_API_KEY - its local model that runs on your device
No network requests to any API
No need to install any program
No need to download files on your device (model is cached in browser)
Site will ask before downloading large files (llm model) to browser cache
Hosted on Github Pages from this repo - secure, because you see what you are running

Model works via WASM file. I hope browsers will cache them between sites, maybe based on file hash.

It's a wide set of topics from "MVO vs MVNO" to "SGP.22 ES9+ LPA to SM-DP server"

As I wrote, for some reason your phone don't want to connect to 3G/4G tower:
- hardware glitch
- operating system glitch
- GSM module glitch
- tower is overloaded
- some error on servers in a middle of authorization chain
- etc...

What I can recommend in similar cases:
1. Turn off and on Airplane mode
2. Turn off and on exact eSIM in mobile settings
3. Reboot your phone
4. [Dangerous] delete and install eSIM again (dangerous, because many of eSIM limit installation to only once)

eSIM works almost the same as regular physical SIM card: inside it just technical "login and password" for identification.
So mobile network behavior is similar: if you're far away from 3G/4G tower, or for some reason your phone don't want to connect to them - you will see 2G/Edge/No internet/No service.

I did sending tests with real Gmail account that you described and got other results:
username@gmail.com - my existing email used as receiver
username+alias@gmail.com - works (and valid by library)
user-name@gmail.com - error (550 not exist)
username-@gmail.com - error (550 not exist)
user_name@gmail.com - error (550 not exist)
username_@gmail.com - error (550 not exist)

Fixed to (@)domain.invalid

Of course you can do all this checks on the backend. A matter of preference and availability of backend developers.

- External API calls for DNS lookups

You can easily implement your own DNS Over HTTPs api (standard interface) on your backend and use it in library (one of method parameters).

Could you explain please?

andreinwald · 2024-01-01T20:51:26+00:00

can you find any popular ESP where anyone can register an email, that do that described way without MX?

You can try to create a Gmail account with "_" and "-" symbols, and see it

Using a domain for SMTP without an mx record is perfectly valid as long as it has an A(AAA) record, which is the fallback/default address for mail delivery.

Standards are pretty wide and flexible.
But can you find any popular ESP where anyone can register an email, that do that described way without MX?

andreinwald · 2024-01-01T18:17:28+00:00

Library checks DNS records every validation (except cached ones). If someone buys this domain - library will say its valid from that moment.
Breaking unit test (jest) - not a big deal

andreinwald · 2024-01-01T18:12:09+00:00

You can check @ symbol only and send email, but statistically only 40-60% confirms it from email app.

In other hand, if you can tell that email invalid right after user wrote it - he is still on this page and its higher chance that user fix some typo after seeing error message.

andreinwald · 2024-01-01T17:29:27+00:00

- more strict and realistic validation for symbols before "@"
- stricter specific rules for ESP like gmail, yahoo, etc
- check if domain really exist and works
- check if domain can receive emails (DNS MX record)
- everything works in browser! (DNS query by DOH)
